1.3Ultra 2 Host System—Power Connection Requirement

You can connect a controller module to an Ultra 2 host system; however, you must connect the power cord of the Ultra 2 host to one of the AC power sequencers in the expansion cabinet that contains the controller module.

You need to order one of the following power cords depending on the type of power sequencer in the expansion cabinet (FIGURE 1-5):

■Ultra™ Enterprise™ expansion cabinet and StorEdge expansion cabinet— part number 530-2197-xx

■56-Inch Data Center expansion cabinet—part number 180-1189-xx (United States) or part number 180-1190-xx NEMA (European)

Caution –Failure to connect the power cord correctly as described here may cause excessive ground current that could damage the system.
